Graduate Training in Imaging Sciences at Washington University Carolyn J. Anderson and Michael J. Welch Mallinckrodt Institute of Radiology, Washington University School of Medicine St. Louis, MO
“The challenge for the 21st century is to understand how the casts of molecular characters work together to make living cells and organisms, and how such understanding can be harnessed to improve health and well-being. …this quest will depend heavily on molecular imaging, which shows when and where genetically or biochemically defined molecules, signals or processes appear, interact and disappear, in time and space.” Dr. Roger Tsien, University of California, San Diego Nature Reviews Molecular Cell Biology 2003
Molecular Imaging – The New Paradigm • The characterization and measurement of biological processes in living animals, model systems and humans at the cellular and molecular level using remote imaging detectors. • Multiple imaging modalities (PET, SPECT, MRI, optical, ultrasound, CT) used to answer scientific questions with imaging • How do we train the next generation of Molecular Imaging Scientists?
Multi- vs Inter- Disciplinary Research • Multi-disciplinary: a group of researchers with differing expertise contributing to a project, and then returning to doing research in their specific expertise • Inter-disciplinary:a research group is performing science that incorporates many aspects of science, with a focus in one area
Current Status of Imaging Sciences Training • Young imaging scientists are typically trained in Chemistry, Biology, Physics, Engineering, etc. • Transition to interdisciplinary research occurs during postdoctoral and/or early faculty years
NIH Initiatives for Training an Interdisciplinary Workforce • Develop interdisciplinary curriculum • Undergraduate, graduate and postdoctoral interdisciplinary training • Create interdisciplinary research teams • INTEGRATION of disciplines is key
Training Programs in Imaging Sciences: Johns Hopkins University Center for Imaging Sciences • Faculty in BME, Electrical and computer engineering (ECE) and Mathematical Sciences • Combines biomedical imaging sciences with computational modeling • Focus on neurological disease imaging • Graduate tracks in Applied Math and Statistics, BME, Comp Sci and ECE
Training Programs in Imaging Sciences: UCLA • UCLA Department of Molecular and Medical Pharmacology • Molecular imaging focus: molecular and cellular mechanisms of normal and diseased organ systems • Faculty have strong biological research interests • UCLA Interdepartmental Biomedical Physics Graduate Program • Faculty from the Molecular and Medical Pharmacology, Radiation Oncology and Radiological Sciences • Graduate degrees in Biological Imaging, Medical Imaging, Radiation Biology and Therapeutic Medical Physics

Principles and Applications of Biological Imaging (PABI) Fall semester 2007 Division of Biology and Biomedical Sciences, Biology 5146, 3 Credits Course Masters: Carolyn J. Anderson and Joe Culver Teaching Assistant: Dr. Monica Shokeen IT Specialists: James K. Kozlowski and Christopher D. Sherman Enrollment : 17 • To emphasize the interdisciplinary nature of imaging sciences. • To conduct a comprehensive survey of the array of interrelated topics that define biological imaging and related topics Course Objective
Principles and Applications of Biological Imaging (PABI) – Lecture topics (90 min) • Imaging math and instrumentation (7 lectures) • Contrast Agents (3 lectures – RaPh, MR and optical) • Tours of imaging facilities (3 lectures) • Imaging applications (9 lectures) • Student Presentations (2 lectures)
Principles and Applications of Biological Imaging (PABI) – Challenges • Very diverse enrollment (biology, engineering, graduate and undergraduate) • Front loading course with math and instrumentation did not go well with biology students • One homework assignment for the first 7 lectures was overwhelming to students • Let students work on homework in groups, with representation from various types of students in each group
Principles and Applications of Biological Imaging (PABI) – changes for Fall, 2008 • Make the course modular based by imaging modality, covering instrumentation, contrast agents and applications for nuclear medicine, MRI and optical imaging • Last module covers topics in neuroimaging • Assign homework after each module (no more than 3-4 lectures for each homework assignment)

Distance Learning WebCT, a web-based resource that can be accessed through internet browser is used for archiving and dispensing information. Currently, a new web-based resource, Moodle, is being used. Use of tablet PC makes remote instruction user friendly Can use this as a “virtual chalk board” for adding notes to slides or giving “chalk lectures” Students from outside universities have enrolled in the ISP courses with tuition waved by the Dean of Arts and Sciences
Imaging Sciences Pathway RetreatsApril, 2006 and April, 2008 • Retreats held at off-campus hotel in the St. Louis metropolitan area • This year’s retreat attracted over 125 participants, and included display of 40 imaging sciences related posters, and talks from industry experts and ISP pathway graduates
Challenges of Interdisciplinary Training • Lack of undergraduates with interdisciplinary training • Teaching interdisciplinary courses to students from diverse academic backgrounds • Survey courses offered in early years of grad training • In-depth courses are for specific aspects of imaging • Encouraging interactions between faculty members of different disciplines • Retreats and seminars • Administration and educational cultural differences must be resolved
Addressing Challenges • Making undergraduate education in Imaging Sciences a priority • Encourage cross-department and school interaction • Jointly sponsored seminars and retreats • Involve faculty from different schools in teaching and curriculum • Require that students have two mentors from two different disciplines (one primary and one secondary)
What will be Achieved by Interdisciplinary Training Programs such as Imaging Sciences? • Integration of disciplines (physical and biological sciences with math and engineering) • A new generation of interdisciplinary scientists with both didactic and practical training • Facilitate communication among scientists across disciplines • Accelerated scientific discoveries
Where do we go from here? • Create a foundation for interdisciplinary pathways and programs • Break down administrative, financial and academic barriers to create a new educational paradigms • Resolve disparities in stipends, payment of tuition, and financial models between programs • Create and sustain an imaging sciences community at WU and other universities
